Timings & File Sizes

The C-5050 Zoom is a relatively quick camera once powered up. Auto focus and lag times are very good, the internal buffer system seems to be well implemented which means that you're nearly always free to take the next shot without the concern over write speed. The C-5050 Zoom's slowest operation is startup, as it always is with extending lens digital cameras, five seconds is slower than most other prosumer level digital cameras. It was also interesting to note that although the new xD-Picture Card performed on par with Compact Flash for small image sizes it was slower with large files (this includes 2560 x 1920 SHQ JPEG's).

Timing Notes: All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 2560 x 1920 SHQ JPEG image (approx. 3.0 MB per image).

The media used for these tests were:

  • 128 MB xD-Picture Card
  • 512 MB Ridata Type I CompactFlash card
  • 1 GB IBM Microdrive Type II CompactFlash card

Auto Focus LAG is (roughly) the amount of time it takes the camera to autofocus (a half-press and hold of the shutter release button), this timing is normally the most variable as its affected by the subject matter, current focus position, still or moving subject etc. This timing is an average.

Shutter Release LAG is the amount of time it takes to take the shot from the moment you fully depress the shutter release button, measured both as a time including auto focus and a time assuming you have already pre-focused by holding a half-press of the shutter release.


Continuous modes

The C-5050 Zoom has two different continuous drive modes. The first (Continuous Hi) shoots at specified 3.3 fps, the LCD monitor is blank during shooting. The second (Continuous) shoots at a specfied 1.7 fps but provides a review of each image after it is taken.

The table below shows the results of our continuous shooting test, indicating the actual frame rate along with maximum number of frames and how long you would have to wait after taking the maximum number of frames before you could take another shot. Timings taken using the 512 MB Ridata Type I CompactFlash card.

*1 Delay after first frame is always longer than shooting speed for subsequent frames, this drags the average fps down.
*2 In a single "burst" (finger held down on shutter release)
*3 You can take a frame as soon as there is space in the cameras internal buffer (writing continues "in the background").
*4 With a fast enough Compact Flash card you can shoot continuously until the card is full at this image size / quality.

As with many digital cameras the average continuous shooting speed is affected by a subtle pause after the first shot, this I can only assume is the camera deciding whether or not you have held the shutter release and are shooting a burst of shots. After the second shot performance levels out until the end of the burst.

As you can see shooting in the 'Hi' mode only allows a maximum of four frames no matter what the selected output size, this must be because the RAW sensor data is being buffered before it is converted to the output format, hence the high speed. Using the normal continuous mode the camera buffers the finished image and so choosing a smaller image size / lower quality means faster continuous shooting a more frames.


File Flush / Display Timing

Timings shown below are the time taken for the camera to process and "flush" the image out to the storage card, the timer was started as soon as the shutter release was pressed (shutter click was heard) and stopped when activity indicator LED beside the storage compartment went out. This means the timings also include the cameras processing time and as such are more representative of the actual time to "complete the task".

The media used for these tests were:

  • 128 MB xD-Picture Card
  • 512 MB Ridata Type I CompactFlash card
  • 1 GB IBM Microdrive Type II CompactFlash card

1024 x 768 SQ2 JPEG Normal 2.3 1.9 3.0 <0.5 <0.5 1.0

Overall write speeds were very respectable, especially considering the size of the image files being transferred. Overall the flash CF card performed best, the xD trailed with a slower overall transfer speed especially with larger files (almost twice a slow storing a RAW file). Microdrive performance was respectable, certainly on par with other Microdrive compatible prosumer digital cameras.


File Sizes

Here's a comparison of the average byte size of some different image size / quality combinations.

Image Type File size *1
(approx.)
Number on a
512 MB card
2560 x 1920 RAW (ORF) 7,300 KB  68
2560 x 1920 SHQ JPEG 3,000 KB  139
2560 x 1920 HQ JPEG 1,200 KB  410
1600 x 1200 SQ1 JPEG High 1,200 KB  354
1024 x 768 SQ2 JPEG Normal 200 KB  2401

*1 All file sizes are an average of three files. As is the case with JPEG it's difficult to predict the size of an image because it will vary a fair amount depending on the content of the image (especially the amount of detail captured). For example, take a photograph of a fairly empty wall and you'll get a small JPEG, take a photograph of a bush with a lot of detail and you'll get a larger image. File sizes here are closer to the later, the larger size of file you should expect.


Battery life

We ran the camera through our new battery life test. This test is designed to be fair and comparative to each camera and battery type:

  • Take 4 shots without flash
  • Wait 2 minutes (50% of the time powering the camera off)
  • Take 1 shot with flash
  • Wait 1 minute
  • Repeat

This test routine was carried out on five different cameras simultaneously. All batteries had been fully discharged and recharged before the test and all cameras were reset to their factory default settings. Here are the results:

Other test notes:
 • LCD monitor is left on during the battery test
 • The camera is powered off half of the time and left on half of the time (switch every 10 iterations)
 • There are now higher capacity AA NiMH batteries available, however in the interests of fair
    comparison we will continue to use our 1600 mAh test set

The C-5050 Zoom did very well, indeed it managed to last longer than any other AA powered digital camera we have tested, three and three quarter hours on a set of 1600 mAh NiMH's is about as long as we could possibly expect. Very good.
